Brake discs STOPTECH or EBC

I've had Stoptech slotted rotors and EBC Reds for three or four years now. They've been great!

StopTech Sport Slotted rotors have taken a ton of abuse for me and I can't recommend them highly enough

May have been overkill but it worked a charm. (ebc yellow stuff, dot5.1, high carbon rotors)

I had EBC disks in the past (not on my Alfa tho) and they were very good in my opinion.

daily driving, you can get a full set of bosch pads from rock auto for ~60$. I like stoptech slotted rotors to help get debris off the pads. they also hold up a bit better than standard blanks. drilled rotors are mostly for looks and can crack much easier under heat unless you are spending big bucks on a high end rotor, which imo isn’t worth the cost.

I have the Stoptech Z23 slotted and drilled rotors with carbon ceramic brake pads. Overall, I’m happy with them. The biggest complaint is that they use undersized brake pads, which is a feature that performance pads have in order to accommodate expansion under high heat. Because they’re undersized, when you brake in the opposite direction that you brakes last, they will “click” as they shift slightly inside the caliper. They don’t do it while driving unless you change direction, but I would have considered less aggressive pads if I knew they would do this. That said, I have had zero issues and great braking performance in spirited driving and emergency braking, over the last 45K miles or so.

I upgraded to stoptech drilled rotors with the posi quiet pads. I'm happy with the performance on street for spirited driving, and they create much less dust than my old Hawk HPS pads.

I got EBC rotors and orange pads. Much better than stock IMO.

So my rotors seem to be warped on my 2020 Civic Si, at least I think so. They feel alright with very light braking, but any amount of hard braking immediately causes wobbling. Pads are definitely low, only about 2-3 mm left, so I figured I should just replace the rotors anyway. I just ordered EBC's Stage 5 kit that comes with slotted and dimpled rotors and yellowstuff pads front and rear for $500 due to good reviews on the Civicx forum. However, I'm reading a lot of people say that slotted/dimpled simply is not worth the extra cost for a street car. I drive pretty hard in the mountains and have felt a pretty substantial amount of brake fade at times so I figured I could definitely benefit from some better heat dissipation, but now I'm starting to regret my decision. Am I wasting my money?

Since I installed the StopTech slotted brake rotors on my 2013 Golf R last winter, every time I've driven in the rain, after cruising long enough such that the brakes get "cold," as soon as I mash on the brake pedal, there is no stopping power whatsoever. Once the brakes "heat up" the response and stopping power are as what I'd expect. On a dry day, this does not happen at all - the brakes are firm and the stopping response is exactly what I'd expect.
